NFPA Water-Based Systems Professional CWBSP Question # 30 Topic 4 Discussion

In a building with an ordinary hazard occupancy and a roof slope as described, calculating the number of sprinklers on a branch line typically involves considering the spacing and the slope's impact on coverage. For 11.5 ft on-center spacing, calculating six sprinklers on a branch line would provide adequate coverage without exceeding maximum spacing requirements.
